ABSTRACT:
A voltage detector detects and indicates simultaneously the voltage levels at a plurality of parts of an object to be measured. A probe formed of electrooptic material having a refractive index changed in the presence of a voltage placed near the object and beams of polarized light are transmitted through the probe and reflected by a polarized beam splitter to a detector for indicating the voltage levels at the parts of the object.
